Generalize this optimization to work on equality comparisons between any two
integers that are constant except for a single bit (the same n-th bit in each).

Reapply r88830 with a bugfix: this transform only applies to icmp eq/ne. This
fixes part of PR5438.

Revert r88830 and r88831 which appear to have caused a selfhost buildbot some
grief. I suspect this patch merely exposed a bug else.

Teach instcombine to look for booleans in wider integers when it encounters a
zext(icmp). It may be able to optimize that away. This fixes one of the cases
in PR5438.
